Balthus
From Memory Alpha, the free Star Trek reference.
Doctor Balthus was a female botanist stationed on board the USS Enterprise-D during the 2360s.
In 2367, Balthus wanted Keiko O'Brien to do a study on the laticifer ontogeny of Kaladian thorn flowers, but Keiko was too busy with other projects. (TNG: "Night Terrors")
